IMPROVEMENT IN JOURNAL-BOXES.

Specification forming part of Letters Patent No. 159,579, dated February9, 1875 application filed May 26, 1874.

To all whom it may concern:

Be it known that we, LEWIS J. IVES and JOHN LEARY, both of Medina, inthe county of Orleans and State of New York, have invented a certain newand useful Improvement in Grindstone-Boxes; and we do hereby declarethat the following is afull, clear, and exact description of theconstruction and operation of the same.

Our invention consists of a removable bearing resting in seats of themain box or casing, and provided with raised surfaces, which receive thejournal of the grindstone, and an intermediate chamber, which receivesthe oil, and provided also with end flanges, which overlap the seats toretain the box in place, as hereinafter described.

In the drawings, Figure l is a plan,with the cover removed. Fig. 2 is alongitudinal vertical section. Fig. 3 is a cross section. Figs. 4 and 5are perspective views of the main box and the bearing.

A is the exterior box or casing, which is of ordinary form, and providedwith a cover, B. This box is provided with two notches, a a, on oppositesides, sunken of sufiicient depth to form seats to receive the bearingfor the.

journal of the grindstone. O is the hearing, which receives the journal.This bearing is made to fit into the seats'a. a, and at the ends areflanges b b, which overlap the seats, and bear closely against the outersides of the main box, as shown, thereby making a close fit, andretaining the bearing from end movement, and also serving to close thespace tightly, and prevent the entrance of water or grit. At each endalso is a raised surface, 0, which receives the journal, and forms thebearing proper to the same, while between them is a depressed space,which forms an oil-chamber, d. The oil-chamber is supplied with oilthrough a duct, f, of the cover.

-We prefer to make the bearing 0 of brass or composition metal, as it ismore effective in use; but it may be made of other material. When fittedin place in the seats a a, the upper surface of the bearing lies flushwith the top of the main box, so that the cover can fit close on top,said cover having a concavity to fit the journal.

Grindstone-boxes of similar form are not new, having been before used,with the journal of the grindstone resting either in a solid or fixedbearing, or onfriction-rollers. The novelty in our invention consists ofthe separate and removable bearing 0, fitting in the seats a a, andconstructed with the bearingsurface 0 c, flanges b b, and intermediatede pressed oil-chamber (Z.

By this construction of the device but a small bearing-surface isexposed to friction, a constant supply of oil is furnished, and thebearing is held firmly against either end or side movement. At the sametime the hearing is removable, and can be replaced when worn.

What we claim as new, and desire to secure by Letters Patent, is-

The combination, -with the interior box or casing A having the notchedseats a a, of the bearing 0 adapted to said seats, and constructed withthe end flangesb b, overlapping the seats a, and with the depressedoil-chamher (1 formed in the bottom of the bearing, all substantially asherein shown and described. In witness whereof we have hereunto signedour names in the presence of two subscribing witnesses.
